To all whom it may] concern: 7

Be it known that 1, WILLIAM ASHTON DoBLE, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Combined Hydraulic Motors and Vacuum-Creating Means for Cleaners, of which the following is a specification.

Within the housing of a hydraulic prime mover of the tangential water wheel type or of a pressure turbine, a very high vacuum is generated, in the tangential water wheel type adjacent the axis of rotation of the wheel, due to the rotation of the wheel with its buckets and the throwing off of discharge and spray water from the wheel, and in the pressure turbine due to the passing of the water in the draft tube.

The present invention has for its principal objects to utilize this vacuum in cleaning the building in which the prime mover is situated, thereby securing an efficient cleaning device withoutthe expenditure of separate power and without the installation of a separate apparatus for the purpose; to provide a vacuum cleaning device which will not require the removal of the dust and dirt collected thereby, as the same will enter the Wheel housing and will be carriedby the waste water in the tail-race.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention attention is directed to the accompanying drawings in which Figure 1 is a side elevation partly broken away of a hydraulic motor housing with my improved device mounted thereon. Fig. 2 is a front elevation of my invention mounted in the casing; Fig. 3 is an enlarged sectional view of my invention disclosing in dotted llnes the cover elevated and a hose inserted in the opening therein. Fig. 4 is a view in elevation of the water wheel connected up with a dynamo.

Referring more particularly to the drawings, the numeral 1 indicates a base supporting the housing of a tangential water wheel 1 and in which is mounted on a shaft 2 journaled in a bearing 3, a water wheel provided on its peripheral edge with the usual buckets 5. A generator 6 or other suitable machinery to be operated, is secured to the shaft 2 exteriorly of the housing and said wheel is operated to rotate the shaft by the force of the water issuing from the nozzle '7 of any well known type and which is preferably mounted in a recess in the base, and said nozzle is raised and lowered by the hydraulic mechanism 8 operated in the usual manner. The water after striking the buckets and having spent its force thereagainst passes out through the tail-race 9 formed in the base 1, and it will be apparent that the rotation of the wheel at high speed, the

throwing off of discharge and spray water from the wheel, and the passing of the water through the tail-race will create a very high vacuum in the housing adjacent the axis of rotation of the wheel.

Mounted within a 7 suitable opening formed in the housing 1 adjacent the axis of rotation of the wheel is a suitable coupling for receiving the vacuum hose, and said coupling is preferably formed of cast metal. The coupling is formed with a curved top wall 10 which terminates in downwardly extending and outwardly flared side walls 11 and projecting upwardly from the top wall and connecting the front edges of the side walls above their lower ends are the flanges 12 and 13 which are secured by bolts 14 to the interior surface of the housing 1 adjacent the peripheral edge of the opening formed therein. A suitable circular front wall 15 is stepped outwardly from the flanges 12 and 13 and the same is of a diameter sufficiently large to occupy the opening formed in the housing, and said front wall is formed in its center with a suitable tapered opening 16 surrounded by an outwardly projecting flange 17, and in said tapered opening is adapted to be inserted one end of a cleaning hose. A cover 18 hinged at its upper edge, as at 19 between lugs 20, projecting outwardly from the front wall 15 and flange 17, is adapted for normally closing the tapered opening when the hose is not inserted therein. A rear or battle wall 21 extends downwardly from the top wall 10 and connects the rear edges of the side walls 11, and said rear wall provides a suction or vacuum chamber within the-coupling which is open at its lower end. Suitable perforations 22 may be provided in the rear wall adjacent its lower edge as disclosed in the drawings.

It will be apparent that the coupling for housing is constructed in such a manner that when it is desired to use thesam'e, it is only necessary to lift the cover 18 and insert the hose in the tapered opening 16. The rear wall 21 prevents the spray Water from escaping through the opening 16 and the lower portion of the chamber being completely open to the interior of the housing and the lower portion of the rear wall being perforated, a maximum vacuum is secured within the coupling or housing without any splash water escaping from the housing through the opening 16 at any time.

The dust and dirt removed by the cleaning hose will be drawn into the wheel housing 1, and will pass therefrom intermingled with the water as it passes through the tailrace and is thus permanently disposed of.

From the above description it will be apparent that I have utilized the suction of vacuum generated within the housing of a hydraulic prime mover for vacuum cleaning purposes, and have thus provided a vacuum cleaner which operates without the installation of separate or special apparatus and without the expenditure of special power.

Having thus described my invention what I claim as new and desire to protect by Letters Patent is 1. The combination with a fixed housing, of a prime power motor situated therein to receive the impact stream from a hydraulic nozzle, a suction hose connection within the housing and communicating with the interior thereof and adapted to receive a hose for the utilization of the suction force of the motor for vacuum cleaning purposes, and means for maintaining normally closed the said hose connection.

2. The combination with a stationarily mounted prime power motor adapted to be operated by an impact fluid pressure, a fixed housing for said motor, said housing being formed with an opening therein for the reception of a suction hose for vacuum cleaning purposes, and means for normally maintaining said opening closed.

3. The means for utilizing the vacuum or suction force within the housing of a hydraulically operated prime motor for vacuum cleaning purposes, the same comprising a suction coupling connected with the housing and communicating with the interior thereof and adapted for the reception of asuction hose, and means for normally maintaining said coupling closed.

4. The combination with a stationarily mounted prime power motor adapted to be operated by an impact fluid pressure,;a fixed housing for said motor, said housing being formed with an opening therein for the reception of a suction hose for vacuum cleaning purposes, a battle wall within said housing adjacent the inner end of said opening, and means for normally maintaining said opening closed.

5. The combination with a stationar-ily mounted prime power motor adapted to be operated byan impact fluid pressure, a fixed housing for said motor, said housing being formed with an opening therein, a coupling mounted in said opening, said coupling formed with a hose recelving connection communicating with the exterior of said housing and also formed with a suction chamber communicating with said hose receiving connection and opening at its lower end into said housing, and means associated with said hose receiving connection for normally closing the same.

6. The combination with a stationarily mounted rotary prime power motor for operation by an impact fluid pressure, a fixed housing for said motor, said housing being formed with an opening in one of its outer walls adjacent the axis of rotation of said motor, a coupling mounted in said opening, said coupling formed with an outwardly projecting hose receiving connection and being further provided with a suction chamber communicating with said hose receiving connection and open at its lower end with the interior of said housing, and a valve for normally closing the outer end of said hose receiving connection.

7. In an apparatus of the character described, the combination of a rotatable wheel having peripheral blades, a nozzle to discharge water onto said blades, a casing for the wheel, said casing having in one of the side walls thereof an opening, a coupling fitted to said opening adapted to receive a hose or the like, and said coupling having a deflector plate overlying the opening, 'sub stantially as and for the purpose described.

8. In an apparatus of the character described, the combination of a casing, a wheel Within the casing having peripheral buckets, a nozzle to discharge Water onto the buckets, one of the side Walls of the casing having an opening therethrough adjacent the periphery of the Wheel and at a point removed from the nozzle, a coupling member fitted to said opening and adapted to receive a hose or the like, a deflector interposed between the inlet opening of the coupling member and said Water Wheel, and a 10 movable closure for said opening.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
